OpenAI CEO Sam Altman's sister, Ann Altman, filed a lawsuit on Monday, alleging that her brother sexually abused her regularly between the years of 1997 and 2006.
The lawsuit, which was filed in U.S. District Court in the Eastern District of Missouri, alleges that the abuse took place at the family's home in Clayton, Missouri, and began when Ann, who goes by Annie, was three and Sam was 12. The filing claims that the abusive activities took place "several times per week," beginning with oral sex and later involving penetration.
The lawsuit claims that "as a direct and proximate result of the foregoing acts of sexual assault," the plaintiff has experienced "severe emotional distress, mental anguish, and depression, which is expected to continue into the future."
The younger Altman has publicly made similar sexual assault allegations against her brother in the past on platforms like X, but this is the first time she's taken him to court. She's being represented by Ryan Mahoney, whose Illinois-based firm specializes in matters including sexual assault and harassment.
